Electrostatic capacitance type input device and calculation method for calculating approach position of conductor

Abstract

An electrostatic capacitance type input device includes: first electrodes arranged in a first direction and extending in a second direction intersecting the first direction; second electrodes arranged in the second direction and extending in the first direction; a storage unit storing first direction detection values obtained through the first electrodes resulting from the change in capacitance between a first conductor and the electrodes, and storing second direction detection values obtained through the second electrodes resulting from the change in capacitance between the first conductor and the electrodes; and a calculation unit, which generates first map values from a first value and a second value obtained, respectively, by processing at least one of the first direction detection values and at least one of the second direction detection values. The calculation unit determines whether the first conductor has approached the first electrodes and second electrodes using the first map values.
